Smartphone Overuse
Smartphone Overuse: _ Average person spends 3 to 4 hours on their smartphone each day. ______ ______ Section-1 Prologue: If there’s anything that most deserves the claim to be a man’s best friend in the modern age, it has got to be the smartphone. The use of smartphones is now a necessity, not a choice. The technological innovation of smartphones and various software has made our lives more convenient. While the bounties of technological innovation have offered limitless opportunities to make life comfortable, their perils cannot be ignored. Worldwide, there are over 6 billion people that have smartphone data plans and it is projected that this will grow to over 7.5 billion by 2026. According to a recent study, almost half of the American population showed hyper-reliance on smartphones, and more than 90% of young people aged 19–29 reported daily use of smartphones. Smartphone devices have the same capabilities […]
Monkeypox (Tinypox)
Monkeypox (Tinypox): _ _ Section-1 Prologue: On May 7, 2022 the world was alerted to a confirmed case of monkeypox in the United Kingdom. Cases have since cropped up across the globe, from Germany and Spain, to the U.S. and Canada. The global monkeypox outbreak, the largest in history, is highly unusual because the virus is circulating widely in countries where it is not normally found. Historically, monkeypox has circulated in remote parts of West and Central Africa. In that context, people normally caught the virus from animals. There was little spread between people. Monkeypox is now spreading widely between people, mostly through close contact during sex among gay and bisexual men. _ Monkeypox is an illness caused by monkeypox virus, which belongs to the Orthopoxvirus genus of the Poxviridae family; other members of Orthopoxvirus genus include variola virus (which causes smallpox), vaccinia virus (used in smallpox vaccines), cowpox virus, […]
Robot
Robot: _ Pepper (above), a humanoid robot developed by SoftBank Robotics, was launched in 2014 and can read human emotions. Over 2,000 companies around the world have adopted Pepper as an assistant to welcome, inform and guide visitors in an innovative way. ____ Section-1 Prologue: What is the first thing that comes to mind when you think of a robot? For many people it is a machine that imitates a human—like the androids in Star Wars, Terminator and Star Trek: The Next Generation. However much these robots capture our imagination, such robots still only inhabit Science Fiction. Science-fiction films and novels usually portray robots as one of two things: destroyers of the human race or friendly helpers. People still haven’t been able to give a robot enough ‘common sense’ to reliably interact with a dynamic world and the independent intelligent machines seen in science fiction are still a […]
DRONE
DRONE: _ Section-1 Prologue: The term “Drone” has been massively overused; most of you have surely seen it time and time again in news and media articles. This term can range from small and cheap hobby aircraft available at Amazon all the way to multimillion weapons systems used on battlefields. Drone is a general term, not a technical one. They are generally equated with unmanned aerial vehicles (UAVs). UAVs can be controlled remotely or autonomously. When we speak about drones, we think about a battlefield, destruction, and death. This is because of the fact that the drones have been conventionally used by the armed forces to drop bombs and destroy enemy targets. These are called the military drones. According to the Bureau of Investigative Journalism, there have been at least 14,040 confirmed drone strikes between Jan. 2002 and Jan. 2019. UAVs are an emerging technology known for their […]
FOOTWEAR
FOOTWEAR: _ _ Section-1 Prologue: Shoes are a product of everyday use that everyone in the world owns; there are more than 20 billion pairs of shoes manufactured each year. Shoes have come a long way in the thousands of years since primitive man first donned bark and animal skins. Originally used to protect feet from harsh temperatures and rough land, shoes have evolved into an article of high fashion and style, a sartorial reflection of class, rank, and wealth. Most people think that wheel invention was the greatest event of the ancient time, but shoemaking takes a very high position on that list too. As they say, “you are what you wear.” And there’s a lot that shoes can tell us about a person. Shoes make the man, they say. Throughout human history, we’ve improved, embellished and refined footwear. We’ve created shoes that impress and inspire, and shoes […]
